Example 1
Referring to fig. 1, the present embodiment provides a dual-chamber oxygen-enriched bottom-blown furnace for metal smelting, which is more energy-saving than the existing products.
Specifically, the double-chamber oxygen-enriched bottom blowing furnace comprises a furnace body; a clapboard 10 is arranged in the furnace body; the clapboard 10 divides the furnace body into a first heating space 11 and a second heating space 12; the bottom of the clapboard 10 is provided with a through channel 13; the first heating space 11 and the second heating space 12 are communicated by a passage 13; the bottom of the first heating space 11 is higher than the second heating space 12; the double-chamber oxygen-enriched bottom-blowing furnace also comprises a feed inlet 21, a burner nozzle 22, an oxygen blowing channel 23 and a hot air circulating channel 24; the feed port 21 communicates with the first heating space 11; the burner ports 22 and the oxygen blowing channels 23 communicate with the second heating space 12; the hot air circulation channel 24 is respectively communicated with the first heating channel and the second heating channel; the hot air circulation passage 24 further includes a fan; the fan blows the hot air of the second heating space 12 into the first heating space 11.
The furnace body is divided into a first heating space 11 and a second heating space 12 with different heights, so that the temperatures of two sides are different, the redundant heat of the second heating space 12 is used for preheating the materials in the first heating space 11, and the preheated materials in the first heating space flow into the second heating space 12, so that circulation is realized, and a large amount of energy is saved. First heating space 11 is used for the burning owing to reinforced, and second heating space 12 has guaranteed combustion efficiency reasonable in design, reduces the oxygen consumption.
Since the temperatures in the first heating space 11 and the second heating space 12 are different in actual production, in order to monitor the whole production process, in this embodiment, the first heating space 11 and the second heating space 12 are respectively provided with temperature measuring holes 27.
